Sltr-haris Type I physl fx low end rad, l arm, 7thK

This code signifies a growth plate fracture at the lower end of the left radius, specifically a Salter-Harris Type I injury, which involves a separation of the epiphysis from the metaphysis without bone involvement. The "subsequent encounter" indicates ongoing treatment for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Use this code for follow-up encounters where a patient is being managed for a previously diagnosed Salter-Harris Type I fracture of the distal left radius that has not united. This would include scenarios such as cast changes, physical therapy evaluations, or surgical planning for nonunion. It is appropriate when the physician explicitly documents nonunion of the fracture.

• Ensure documentation clearly states "left arm" and "nonunion" for accurate code assignment.
• This code is for subsequent encounters only; an initial encounter would use a different seventh character.
• Verify the specific Salter-Harris type (Type I in this case) is documented to differentiate from other growth plate injuries.
